[HELP][Yamaha XV1000SE] What is this part's name ?

Hi,

I have to change, on my good old '83 XV1000SE, a part inside the
carburetors.
It's marked in red on this design :

Unfortunately I do not know this part's name, so I cannot search it on
the net.

Could somebody help me ?
Thanks ))

That's the diaphram.

Hi Mark,

Yes I am outside the USA, in France.
It had this drawing in a PDF file I downloaded on a web site (this PDF
contains the whole technical manual of the XV series).

Could you e-mail or post a link for me to get that PDF.
I have a 1981 XV920RH, and HAD a Factory Shop Manual. I could not
find it when I recently looked for it.
I went to the Yamaha web site and looked up parts numbers and
breakdowns as they are shown in their "fiches", which included the
technical service bulletins, but the drawings are difficult to get in
a easy to read format.

Thanks in advance.
